Acts 8:9: How to spot false teachings?
What can Acts 8:9 teach us about discerning false teachings today?

The Text

“Now a man named Simon had previously practiced sorcery in the city and amazed all the people of Samaria. He claimed to be someone great.” (Acts 8:9)


Snapshot of Simon the Sorcerer

• Practiced visible, impressive “signs” apart from God’s power

• Captivated an entire city—his influence was widespread, not fringe

• Promoted himself: “He claimed to be someone great”

• Enjoyed praise more than truth (vv. 10–11 show people calling him “the Great Power of God”)


Key Warning Signs of False Teaching Today

1. Self-exaltation over Christ-exaltation

– Simon drew attention to himself. True servants say, “He must increase, but I must decrease” (John 3:30).

2. Attraction to spectacle instead of Scripture

– Sorcery produced wonder, yet lacked truth. Compare with 2 Thessalonians 2:9–10, where counterfeit “signs and wonders” deceive those who refuse the love of the truth.

3. Popular approval as the benchmark for authority

– “All the people” followed Simon. Majority enthusiasm never guarantees orthodoxy (Matthew 7:13–14).

4. Power without repentance

– Simon’s sorcery impressed but could not save. Authentic ministry calls people to turn from sin (Acts 2:38).

5. A blurred distinction between God’s power and occult or fleshly power

– Scripture forbids “sorcery” (Galatians 5:19–21). Any teaching that mixes biblical language with unbiblical sources must be rejected.


How to Discern and Guard Ourselves

• Test every spirit (1 John 4:1)

• Measure teaching against the whole counsel of God (Acts 17:11)

• Look for fruit: sound doctrine produces holiness, not merely excitement (Matthew 7:15–20)

• Reject any “gospel” that differs from the apostolic message, even if accompanied by miracles (Galatians 1:8)

• Stay anchored in local church accountability—shepherds protect flocks from “every wind of doctrine” (Ephesians 4:14)

• Cultivate personal familiarity with Scripture; deception thrives on biblical illiteracy (Colossians 2:8)


Encouragement for Today

Acts 8:9 reminds us that counterfeit voices will always arise, but God has provided everything necessary for discernment. The Holy Spirit, the written Word, and a community committed to truth equip believers to spot self-promoters, sift flashy claims, and cling to “the faith once for all delivered to the saints” (Jude 3).
